Abstract

This study investigated the effect of water immersion and passive recovery on blood lactate and subsequent swimming performance. Ten trained female swimmers, age (17.8 ±2.2), height (164.55.8 cm), weight (59.29.9 kg), %BF (22.41.7) and BMI (21.85.4kg/m2) completed three experimental trials differing in 15 min recovery intervention three times a week with 48 hrs distance: land (sitting near the pool) (PAS), contrast water therapy (CWT) (alternating hot 40,2 min/cold 23,1min) and cold water immersion(CWI)(23 ). Before and after 100meters front crawl and each three
minute during of recovery blood lactate, heart rate and skin temperature were
recorded. Participants repeated 100meters front crawl after the recovery.
Repeated measure and LSD were used for data analysis. In all statistical
analyses, the threshold for significance was set at (p≤0.05). Results showed
that Heart rate decreased significantly in CWI toward PAS. Lactate removal was
largest in CWT compared to the PAS. Skin temperature and fatigue decreased
significantly after immersion and significant difference was observed in
subsequent performance after immersion toward PAS. So it seems immersion
conditions, can enhance quality of recovery.

Abstract
The present study was aimed to determine the effect of cold-water immersion and (TDCS) during the recovery period on blood lactate changes in and subsequent performance of professional male swimmers. For this purpose, 20 male participated in this study in two days with an interval of 48 hours. The two-hundred meter breaststroke was performed every day and then the subjects participated in one of the protocols, an anodic stimulation (with intensity of 2 mA)or the artificially exposed to anodic stimulation on the first day, and on the second day they were experienced the cold water immersion (12° C).The subjects' blood lactate was measured. Finally, in order to measure the effect of the investigated methods on their performance, the 200-meter swim was repeated. To analyze the data dependent t-test and analysis of covariance, LSD follow-up, analysis of variance with repeated measures, were used. The results of this study indicated that swimming performance significantly improved only in the TDCS group, with a reduction in the record time (P = 0.001). Blood lactate showed a greater decrease in the cold water immersion group (P = 0.001)
